Description

[Detailed description of the invention] (Industrial application field) This invention relates to an inhalation treatment device, and its purpose is to collect and treat industrial waste (sludge, wet earth and sand, dust) and general waste, etc. It is an object of the present invention to provide an inhalation processing device that can efficiently collect and process objects depending on the shape of the inhaled object.

(Prior Art and Its Disadvantages) Conventionally, there is one shown in FIG. 5 as one type of inhalation treatment device.

That is, a suction mechanism, for example, a roots blower c, is disposed in the front part of the loading frame b of the vehicle a, and a storage tank d is disposed in the rear part, and the drive shaft e of the roots blower c and the drive shaft of the vehicle a are connected.
The PTO shaft f is interlocked and connected to the PTO shaft f through an appropriate interlocking mechanism, and the front part of the storage tank d is raised and lowered so that it can be raised and lowered as a whole. A partitioned tank g formed by partitioning the mist catcher and noise-reducing water tank is installed,
The storage tank d is connected to a wet dust collection tank, the inlet of the roots blower c is connected to the wet dust collection tank, and the outlet of the Roots blower c is connected to a mist catcher and silencing water tank to perform a series of dust collection functions. There is an inhalation treatment device that has a suction pipe h that is ejected from the body.

By the way, in the above device, since the air volume and head of Roots blower c used as a suction mechanism are constant, when suctioning objects that require a large air volume, such as scale or powder, a large air volume is required. It was necessary to prepare a Roots blower that can obtain the necessary high vacuum pressure when inhaling highly viscous substances.

Therefore, in order to accommodate these two Roots blowers, two driving devices, piping, bases, and peripheral devices for the driving devices are required, making the entire suction processing device larger and heavier. This method has disadvantages in that it requires a large installation surface and the strength of the installation location must also be increased.

In addition, as an inhalation treatment device that focuses on the shape of the inhaled object, there is a technology disclosed in Japanese Utility Model Application No. 168714/1982 or Japanese Utility Model Application No. 22870/1987, but the former is a technology that separates dust. It attempts to completely inhale the inhaled dust using two separators.
Although it is possible to inhale finely divided intake dust, it is difficult to inhale highly viscous substances. Cleaning machines also had the disadvantage of difficulty in inhaling highly viscous substances.

Furthermore, as a technology used in pump equipment,
No. 49-77201, Japanese Utility Model Application No. 50-114601, etc. are disclosed, and these techniques are pump devices that can convert between parallel motion and series motion using a switching valve.

However, the former uses two pumps, and the latter uses vortex chambers on both sides of the motor, making the equipment larger and requiring a compact shape for suction processing. The device could not actually be used.

(Means for solving the problem) This invention was made to solve the above-mentioned drawbacks, and a suction mechanism is operably connected to a single drive source, and at least a wet dust collector is installed near the suction mechanism. The two tanks, the tank and the mist catcher and silencing water tank, are either integrally combined or placed separately in close proximity, and the outlet of the wet dust collection tank is communicated with the suction port of the suction mechanism, and the discharge port of the suction mechanism is connected to the tank. In the suction processing device, which is connected to the inlet of a mist catcher/silencer tank and the discharge port is opened to the atmosphere via the outlet of the mist catcher/silencer tank, the inside of the suction mechanism case is blocked by a partition wall. There are two spaces, 1 space and 2 space, and each of the two spaces rotatably accommodates a suction vane driven by the drive source through the same shaft, and the suction port of the first space is A pipe is connected to the outlet of the wet dust collecting tank, and a pipe having a switching valve is branched from the middle of the pipe and connected to the inlet of the second space, while the outlet of the second space is connected to the outlet of the second space. is connected to the inlet of the mist catcher and silencing water tank by a pipe, and from the middle of this pipe, a pipe having a switching valve is branched and connected to the discharge port of the first space, and these branches are further connected to each other. By providing an inhalation processing device characterized in that two pipes are connected to each other by a bypass pipe having a switching valve and can be freely combined in parallel or in series via a switching valve device provided on these pipes, the previous method can be improved. solve the shortcomings of

(Function) According to this invention, the suction force of the suction mechanism sucks the inhaled substance from the suction pipe, and the inhaled substance is sent to the mist catcher/silenced water tank through the wet dust collecting tank and the suction mechanism in sequence. It is to be collected.

In this case, the inside of the case of the suction mechanism is divided into two spaces, and suction blades are rotatably housed in each space, and the two spaces can be freely arranged in parallel or in series via a switching valve. It allows them to be combined.

Therefore, when the above-mentioned spaces are combined in parallel even though it is a single suction mechanism, a large air volume can be obtained and it is possible to suck in scale, powder, etc., and when the above-mentioned spaces are combined in series, high airflow can be obtained. A degree of vacuum is obtained, making it possible to inhale highly viscous substances.

Furthermore, since the suction vanes housed in the two spaces are driven from the same axis by the drive source, there is no need to use multiple drive sources even though there are two suction spaces.

(Example) Hereinafter, an example of this invention will be described in detail based on the drawings.

FIG. 1 shows a flowchart of the suction processing device according to the embodiment of this invention, FIG. 2 is a partially cutaway side view of the suction mechanism (roots blower in the illustrated embodiment), and FIG. The figure is a sectional view, and FIG. 4 is a flow explanatory diagram of the suction mechanism.

A indicates an inhalation processing device, and this inhalation processing device A has a suction mechanism 2 as a suction mechanism connected to a drive source 1 so as to be interlocked, and a cyclone 3 and a wet dust collection tank 4 are installed near the suction mechanism 2. In addition, three tanks, a mist catcher/silencer tank 5, are arranged separately and close to each other.
The outlet of the cyclone 3 is communicated with the inlet of a wet dust collection tank 4, and the outlet of the tank is communicated with the suction port of the suction mechanism 2, and the discharge port of the suction mechanism 2 is used as a mist catcher/mute water tank 5. The discharge port is opened to the atmosphere through the outlet of the mist catcher/silence tank 5, and the storage tank 28 is attached to the inlet of the cyclone 3 via the flexible connecting pipe 6. A flexible suction pipe 29 is attached to the suction port.

That is, the inhalation treatment device A in this invention
A storage tank 28, a cyclone 3, a wet dust collecting tank 4, which can suck the inhaled substance from the suction pipe 29 and dump the inhaled substance by the suction force of the suction mechanism 2;
The mist is collected in a mist catcher/silenced water tank 5 via a suction mechanism 2 in sequence. Note that the cyclone 3 is not necessarily required, and when the cyclone 3 is not used, the flexible connecting pipe 6 is connected to the inlet of the wet dust collection tank 4. It is also possible to make a modification in which only the storage tank 28 is separated from the entire path of the same frame (stationary type or vehicle-mounted type), and only the storage tank 28 is made into an independent stationary type or vehicle-mounted type.

In the gist of this invention, the structure of a Roots blower as a suction mechanism, which is a main constituent device, will be explained based on FIGS. 2 and 3.

That is, this Roots blower 2 divides the inside of the case 7 into a first space 9 and a second space 10 via a partition wall 8, and has a first suction port 11 and a first suction port in the first space 9.
The discharge ports 12 are arranged respectively, and the second space 1
A second suction port 13 and a second discharge port 14 are provided at each of the two ports.

In addition, a shaft 15 that can penetrate the first and second spaces 9 and 10 is rotatably supported horizontally at an upper position in the case 7, and the shaft 15 is interlocked and driven from the power source 1 via an interlocking belt. It is configured as much as possible.

Further, a shaft 17 that can be inserted into the first and second spaces 9 and 10 is rotatably supported horizontally at a lower position in the case 7, and the shaft 17 is interlocked and driven from the shaft 15 via an interlocking gear 18. It is configured as much as possible.

Further, in the first space 9, the suction vanes 19 are connected to the shaft 15 and the shaft 17 in a mutually relative state, and in the second space 10, the suction vanes 19 are connected to the shaft 15 and the shaft 17 in a mutually relative state. They are each installed consecutively.

That is, when the suction vane 19 is rotationally interlocked from the single power source 1 through the interlocking of the shafts 15 and 17, the rotation from the first suction port 11 to the first discharge port 12 is interlocked.
This is to generate a conveying air from the second suction port 13 to the second discharge port.

Next, an embodiment of the piping structure constituting the switching valve device in the suction processing device A of the Roots blower 2 will be described as follows.

That is, the tip of the pipe 20, whose one end is connected to the wet dust collection tank 4, is connected to the first suction port 11, and the tip of the pipe 21, whose one end is connected to the mist catcher/silencer tank 5, is connected to the first suction port 11. The two discharge ports 14 are connected in communication. Further, the middle part of the pipe 20 is connected to the second suction port 13 via a pipe 23 having a valve 22, and the first discharge port 12 is connected to the second intake port 13 via a pipe 25 having a valve 24 in the middle part. pipe 21
A connection is made in the middle.

Further, a point P1 downstream from the valve 22 in the pipe 23 in the flow direction P and a point Q1 upstream from the valve 24 in the flow direction Q in the valve 25 are connected via a valve 26 by a bypass pipe 27.

Although this invention was not specifically made clear in the above embodiments, it is not limited to a stationary type, but may be mounted on an automobile.

To use the suction treatment device configured as described above, for example, if a high vacuum pressure of -700 mmHg or more is required in the suction treatment device A system, the valves 22 and 24 are closed and the valve 26 is closed. It is preferable to open the first space 9 and the second space 10 to communicate in series. In this case, highly viscous industrial waste can be inhaled. Further, when generating a large air volume in the suction processing device A system, the valve 26 is closed and the valves 22 and 24 are opened to connect the first space 9 and the second space 10 in a parallel state. good. In this case, it can be used suitable for inhaling objects such as scale and powder that require high wind speed for collection work.

(Effects of the invention) As detailed above, the suction processing device according to this invention can obtain both a large volume of air and a high degree of vacuum, so it can be used efficiently depending on the shape of the material, such as powder or highly viscous material. Can be inhaled.

Further, since the drive source according to this invention may be a single one and the suction mechanism may be of the same size as a conventional suction mechanism, the entire processing apparatus can be made smaller and lighter.

Therefore, the installation area is small and the strength of the installation location is also small.
